Single-celling

Single-celling is the practice of assigning only one inmate to each cell in a prison.

John Howard has been credited as establishing the practice of single-celling in the United Kingdom and, by extension, in the United States.

[2] Critics of single-celling suggest that the practice imposes psychologically harmful isolation on inmates, while advocates argue that single-celling alleviates many of the inmates' discomforts.

The practice in many prisons of allowing general population prisoners to freely intermingle during normal hours diminishes the critics argument, while single celling gives prisoners a (relatively) safe place to retreat.

This provides additional security to potentially at risk individuals.
